P1/D1 - ADVANCED TECHNOLOGIES

New ES-LINK4 enables broadband transmission

ES-LINK4 ESOTERIC has developed an original, state-of-the-art transmission format called ES-LINK4, which allows DSD and 352.8kHz/48bit PCM ultrawideband digital transmission using an HDMI cable. ES-LINK4 performs a large part of the digital signal processing on the sending side, greatly reducing the digital signal processing load on the D/A converter. In addition to ultra-wide bandwidth, we sought high sound quality through our "Pure D/A" concept, in which the D/A converter specializes in its original function of D/A conversion processing.

The outstanding expressive power of 36-bit D/A processing 36-bit D/A processing

The D1 applies a 36-bit D/A processing algorithm that converts PCM signals to analog signals at a high resolution of 36 bits by combining several 32-bit DAC devices. The tone of the high-bit data is used for faithful analog conversion. The resolution of 32-bit encoding is 256 times higher than that of 24-bit encoding, and 36-bit encoding gives an amazing resolution level that is another 16 times higher - a total of 4,096 times higher than the resolution of 24-bit encoding. Producing even finer bit tones minimizes operational error for outstanding expression of even subtle music signals.

A new dimension of isolated clock technology

The clock circuit, which supplies highly accurate reference clock signals to a digital circuit, can be considered the core unit of a digital player. The clock circuit of the P1 and D1 is completely independent of other circuits, including its power source and ground, enabling pure clock signals to be supplied to the system. The voltage controlled crystal oscillator (VCXO) was developed especially for the P1 and D1 in a joint effort with Nihon Dempa Kogyo (NDK), a major manufacturer of crystal oscillators. For a high-precision custom clock device worthy of leading models, high sound quality playback is provided thanks to an extremely low level of phase noise and a crystal element that is even larger than before.

High-accuracy clock sync

Jitter is reduced by connecting the P1 and D1 with a BNC cable for clock sync (synchronized playback). ESOTERIC's original technology for direct master clock linkage without Phase-Locked Loop (PLL)* is also supported. This technology enables pure clock processing, achieving a clear and accurate stereo image and ultra-clear sound quality.

An even more sophisticated level of system operation is possible by connecting the high-precision G-01 rubidium master clock (sold separately). This master clock supports clock sync for a variety of frequencies to suit your sound-quality preferences, including master clocks (22MHz/10MHz) and WORD clocks (44.1kHz/88.2kHz/176.4kHz).

*This master clock is a digital audio output reference clock (22.5792MHz) generated within the high-accuracy clock module of the D1. The system also uses this master clock as the clock of the digital output circuit supplied directly to the P1 without passing through the P1's internal PLL circuit. It also supports the LINK 10MHz direct master clock using the 10MHz clock supplied from the G-01 (sold separately).

VRDS-NEO "VMK-3.5-20S"

VMK-3.5-20S ESOTERIC is justifiably proud of this VRDS-NEO transport mechanism. Remarkable improvements in readout accuracy have been achieved by utilizing a high-precision turntable and correcting the disc surface shake occurring during disc rotation. The P1 features the VMK-3.5-20S VRDS-NEO with a refined drive circuit design. A pair of selected ball bearings is used in the spindle shaft bearing assembly, and there is a micron-level accuracy duralumin turntable with a 20 mm-thick steel turntable bridge for a total mass of 5.2 kg. In addition, the highly trusted mechanism of the P1 has been further refined with a high-magnetic-flux-density magnet-driven coreless three-phase brushless spindle motor, thread feed control (which evolved from the concept of the premier P-0 series), and a sliding-shaft-structure pickup that ensures that the laser beam is always at a right angle to the disc.

VS-DD* spindle servo driver

VS-DD The P1 uses the VS-DD dedicated spindle servo driver to drive the spindle motor that functions as the core unit of the VRDS-NEO mechanism. Using a three-channel discrete amplifier circuit to optimize the current waveform supplied to the motors, the VS-DD suppresses vibrations, enabling smooth spindle drive operation and highly precise servo control. The dedicated toroidal power supply unit is mounted in a separate power supply unit housing, enhancing noise isolation effects.

*VS-DD=VRDS Spindle Discrete Driver

Two-chassis structure for main unit and power supply unit

Following the concept employed in our trademark P-0 series, a two-chassis structure is used in the traditional ESOTERIC flagship model. The power supply unit has been expanded to full-size, making it possible to include even more extravagant power supply circuits. A total of four independent toroidal power transformers are installed to supply clean and stable DC power to each circuit (VS-DD circuit, drive mechanism drive circuit, digital output circuit, and clock circuit).

MAIN UNIT POWER SUPPLY UNIT

Extensive material utilized both internally and externally

The inside of the main unit chassis has a double-deck structure and 3D optimized chassis construction connecting each circuit block with the shortest signal paths. Thick aluminum materials are used for the exterior, and the 5 mm-thick steel bottom chassis is supported at four points on original ESOTERIC pinpoint feet. Vibration is effectively controlled and thorough measures have been taken for rigidity.

Various digital output terminals

The P1 is equipped with five types and seven channels of digital output terminals (ES-LINK x 2, XLR x 2, coaxial x 1, i.LINK 4p/6p x 1 each), including a new dedicated ES-LINK4 terminal and dual XLR terminals supporting past.versions of ES-LINK.

ESOTERIC-HCLD*: ESOTERIC's own output buffer circuit featuring fortified current transmission

ESOTERIC-HCLD A high-speed current transmission capability is the most important factor of an analog output circuit for transmitting a wide dynamic range of music signals downstream without deficiencies. For the ultimate performance as a line driver, the output buffer amplifier circuit of the D1 makes extensive use of materials and is configured with its own board separate from the D/A converter. The current output capability is high, and the high-performance elements adopted for the slew rate, which indicates response speed, boast the incredibly high speed of 2000V/㎲. The ability to supply instant current is maximized with an extravagant buffer circuit configuration utilizing one circuit for RCA output and one circuit each for hot and cold connections for XLR output. With the ESOTERIC-HCLD, the D1 reproduces the dynamism of music with breathtaking reality.

*HCLD=High Current Line Driver

High sound quality through the separation of digital and analog circuits

All analog circuits (DAC circuit analog portion, HCLD buffer circuit, etc.) are electrically separate from the digital circuits. This further enhances the clarity of sound quality by preventing the intrusion of digital noise.

Large toroidal transformers boasting high speed and surplus power supply capacity

Two large toroidal power supply units are installed for the digital and analog circuits, enabling high-efficiency and high-power drive operation in addition to low noise and low distortion. Stable and clean power is supplied to each circuit block by strong power supply circuits incorporating multiple large capacitors.

Wide-ranging D/D conversion functions to handle many source types

In addition to playback in the original sampling frequency, the D1 has functions for x2, x4, and x8 up-conversion of PCM digital signals. There are also various D/D conversion modes for PCM format (PCM-to-DSD conversion function, etc.).

Seven types and eight channels of digital input that support high sampling rates

To enable connection to an extensive range of devices, the D1 is equipped with wide-ranging digital inputs of seven types and eight channels (ES-LINK x 1, XLR x 1, i.LINK 4p/6p x 1, USB x 1, coaxial x 2, optical x1), and can be used for high-sampling-rate sources of up to 24-bit/192kHz. In addition, XLR x 2 supports high-sampling-rate/high-bit inputs of 48-bit/192kHz (ES-LINK3) and 24-bit/384kHz (Dual AES 8Fs).
